Firewall UV System Functional Test
WARNING! ULTRAVIOLET RADIATION. Protect your skin and eyes against ultraviolet rays.
Never look directly at an operating UV light. Do not remove from housing when light is on. Always
disconnect lamp before removing from the housing.
6. Turn on red power switch. Check that UV light ignites by looking reflection of light on finger just
below the tip of the faucet. The blue glow around Firewall housing indicates that the lamp is lit.
7. Disconnect the UV lamp connector and verify the Firewall UV lamp alarm annunciates for 20
seconds and status LED goes out. Reconnect and cycle power off for 10 seconds. Disconnect power
supply and reconnect to clear alarm and reactive the Firewall system.
Sanitize
Sanitize using Aquadosa sanitizing solution or other approved sanitizer throughout the cold, sparkling
and or ambient water circuits. Follow all instructions on the sanitizer and flush with fresh water
through the faucet until taste and odour is acceptable. Test the water using test strips to ensure no
sanitizer is left in the WL3FW.
WARNING! USE PROPER PERSONAL PROTECTIVE EQUIPMENT
Always ensure proper ventilation and use proper personal protective equipment such as gloves and eye
protection when using chemicals. Refer to Material Safety Data Sheet for specific requirements of each
chemical product. Take all necessary precautions to prevent sanitizer from contacting eyes, clothing, and
any other surfaces in could damage.
CAUTION! USE SANITIZER COMPATIBLE WITH STAINLESS STEEL AND ACETAL PLASTIC.
Do not allow the sanitizer solution to remain in the system for more than 15 minutes unless otherwise
directed by the sanitizer manufacturer.
8. We recommend using Aquadosa sanitizer, 60ml dose is enough to sanitize the machine. See
manufactures instructions for any other sanitizing solution used.
9. Remove sump and pour sanitizing solution into filter sump and feed into ambient or sparkling and
cold circuits by first dispensing 3 seconds of ambient and then dispensing out 500 ml of cold or
sparkling water. Ensure green switch (compressor/heater) is OFF.
Flush the Sanitizer from the Machine
10. Flush the cold and ambient or sparkling circuit. Run 10 Litres of water through the faucet by
dispensing cold water to dilute and remove the sanitizer from the circuit. You may use test strips to
evaluate the water to ensure all sanitizer has been flushed. Once the sanitizer odour/taste has been
flushed out of the cold side of the machine, flush the ambient circuit.
Note: There is a 1 minute maximum continuous dispense timer as safeguard. Release and reapply if
timeout occurs during dispensing process.
11. The sanitization process for the cold and ambient or sparkling circuits is now complete.
